Printer Cartridges Drying Early on HP Deskjets
Note that unless the cartridge is almost empty
anyhow, it can usually be revived by patting off the caked ink with
a damp lint-free cloth and then gently blowing in the vent hole
on top until a drop of ink appears at the print head. Sometimes
this may have to be done more than once. NEVER poke anything into
that vent hole or you will have a mess!

HP had a free upgrade kit for the 560 to solve
this, maybe for the 500 as well. It was a replacement for the silicone
rubber park-position nozzle seal. Also remember that the 500 came
with a cartridge storage box with an elaborate rubber seal in the
bottom; they encouraged you to remove the cartridge from the printer
and put in the box whenever it wasn't in active use to prevent dry-outs.
Finally, HP cartridges have expiration dates - and they mean what
they say: If they're out dated, they work poorly or not at all.
